Honda Spree and Elite 50 Forums

Can't get fuel to the carb on 85 spree. Lines are clean. Removed the fuel valve. Problem appears to be diaphragm. Will I need to replace valve? Is it possible that there is inadequate vacuum pressure to engage diaphragm? Where can I get the valve, if needed? Thanks.

I'm not sure that it can be rebuilt... I would check eBay or email Greg ( uspmale@yahoo.com ) for the part, you could always contact your local Honda deliership too (might be suprised what parts are still stocked).

Yes, low vacuum (or bad compression) could cause fuel delivery probelms... but I'd error on the valve vs. compression issues. You could always do a compression check.

Just put your month on the vacuum line and suck if gas comes out it works, if not then no.

but don't suck on the gas line...

Of course not, there is to lines, the one directly under the fuel valve is the vacuum, thats the one you want to suck, also remember to remove the fuel line to see if gas comes out, just a little sucking will cause a lot of gas to pour out if the fuel valve is working properly, thats from experience.
